Module: SharedEnvExtension
- Extended by:
- T::Sig
- Defined in:
- extend/os/mac/extend/ENV/shared.rb,
extend/os/linux/extend/ENV/shared.rb,
extend/ENV/shared.rb
Overview
Homebrew extends Ruby’s ENV
to make our code more readable.
Implemented in SharedEnvExtension and either Superenv or
Stdenv (depending on the build mode).

Prepends a directory to PATH
.
Is the formula struggling to find the pkgconfig file? Point it to it.
This is done automatically for keg-only formulae.
ENV.prepend_path "PKG_CONFIG_PATH", "#{Formula["glib"].opt_lib}/pkgconfig"
Prepending a system path such as /usr/bin is a no-op so that requirements
don’t accidentally override superenv shims or formulae’s bin
directories.
ENV.prepend_path "PATH", which("emacs").dirname
